ARM: tegra: fix Tegra186 SDHCI clock/reset names
The Tegra SDHCI binding dictates that the reseet name for the Tegra SDHCI clock be "sdhci" not "sdmmc", and that the clock is accessed by index rather than by name. Fix the Tegra186 DT and MMC driver to honor this. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>
